R: convert variable to csv string

Question

I would like to know how to convert a variable in R to csv string.

> x = c(1:10)
> a = write.csv(x)
\"\",\"x\"
\"1\",1
\"2\",2
\"3\",3
\"4\",4
\"5\",5         


        

Answer 1

Here's an alternative, even easier:

foo2 <- capture.output(write.csv(matrix(1:6,nrow=2), stdout(), row.names=F)) 
foo2
## "\"V1\",\"V2\",\"V3\"" "1,3,5"                "2,4,6" 

Probably what you want is:

foo2[-1,]    
## "\"V1\",\"V2\",\"V3\"" "1,3,5"                "2,4,6" 

Answer 2

Things can be so simple ....

 > zz <- textConnection("foo1", "w") 
 > textConnectionValue(zz) 
 character(0) 
 > write.csv(x, zz) 
 > textConnectionValue(zz) 
 [1] "\"\",\"x\"" "\"1\",1" "\"2\",2" "\"3\",3" "\"4\",4" 
 [6] "\"5\",5" "\"6\",6" "\"7\",7" "\"8\",8" "\"9\",9" 
 [11] "\"10\",10"
